Slip-Resistant Metal Bar Gratings

Overview

In the design and construction community, ALGRIP Slip-Resistant Metal Bar Gratings are viewed as the preferred flooring of choice for applications requiring an open or permeable walking surface. Unique laser-welded deposits deliver unparalleled durability and traction making this technology an intelligent choice for demanding environments, especially where exposure to outdoor elements is a factor. ALGRIP grating is designed for easy cleaning and used extensively throughout many different industries.

Design Features

Available in a wide range of styles, spacings and finishes, ALGRIP Slip-Resistant Metal Bar Grating is an open metal flooring designed to provide maximum protection against slips and falls in conditions where the penetration of light, water or air is considered beneficial.

Ross’ patented CNC laser deposition process applies more than 1,000 rugged, custom-alloy deposits per square foot in a highly precise and uniform pattern. The superior bond strength of these deposits not only increases the useful product life, but also allows nearly any type of onsite fabrication without compromising the traction providing surface. And the smooth area between raised deposits helps deter the pooling of liquids and trapping of solids, which results in a product that exhibits exceptional self-cleaning characteristics.

ALGRIP is an ideal choice for a variety of applications requiring slip-resistant walking surfaces, such as:

Work/Pedestrian Platforms

Mezzanines/Catwalks

Inclined Ramps

Bridge Decking/Walkways

Utility Vault Covers

Sidewalk/Culvert Covers

Steps and Stairs

Trench Covers

Pit Covers

Industries

Thousands of companies have chosen Algrip products to help mitigate their exposure to slip and fall risks. Algrip Metal Bar Grating is ideal for a wide range of project applications and industries including:

Technical Data

ALGRIP Slip-Resistant Metal Bar Grating is manufactured using technologically advanced machinery developed by Ross to ensure the highest level of quality and consistency. We start with the base material that best suits your application. Choose from various grades of lightweight aluminum, corrosion-resistant stainless or durable carbon steel in bar stock form. Then select the method of assembly that best suits your application -Type “W” Welded Steel, Type “PS” Pressure-locked Swaged, Type “PD” Pressure-locked Dovetail – along with the desired size, spacing and finish.

Next, we laser-weld a minimum of 1,000 anti-slip deposits per square foot to the traffic side of the selected material. These welded deposits penetrate the metal substrate to produce a permanent, sub-surface bond tested to a maximum hardness of 60 on the Rockwell C Scale and a maximum static coefficient of friction of 0.97 (COF) in accordance with ASTM C1028-89. Finally, the grating is custom fabricated to meet the size and finish requirements of your project’s specifications. The result is a solid metal grating with durability and slip resistance properties like no other.

Type “PS” Swaged Pressure Locked Grating: Cross bars are inserted into pre-punched holes in the bearing bars and hydraulically swaged to lock the bars in place. Swaging is the preferred method of assembly for the manufacture of close mesh carbon steel, stainless steel and aluminum gratings.

Type “PD” Dovetail Pressure Locked Grating: Assembled by inserting pre-punched bearing and cross bars into an “egg-crate” configuration and deforming the cross bars under intense hydraulic pressure. Allows for the manufacture of gratings with custom spacings.

Installation Considerations

Product can be fabricated, formed, cut and welded without affecting the traction-providing surface, therefore allowing for a wide range of installation methods.

Due to the high hardness of the surface, tooling used in fabricating ALGRIP Metal Bar Grating may experience wear rates higher than normal. Use of tooling designed for high hardness materials is recommended.

Maintenance

ALGRIP Metal Bar Grating is virtually maintenance free, requiring little more than proper cleaning of dirt and debris from the flat, smooth area between deposits.
